Field of the Invention The present invention relates to a fluid separation device, and more particularly to a fluid separation device for separating blood. [Prior Art] Conventional fluid separation devices are generally complicated in construction, such as the fluid separation device disclosed in U.S. Patent No. 6,548,788, which has a microvalve design on the cassette for controlling the flow of fluid. However, since the microvalve must be fabricated by micromachining, the conventional fluid separation device cannot be fabricated by plastic injection molding, and the cost is high. Similarly, U.S. Patent Nos. 5,061,381 and 5,098,417 disclose other types of fluid separation devices which are too complicated in construction and are therefore relatively expensive. SUMMARY OF THE INVENTION The present invention provides a fluid separation device for solving the problems of the prior art, comprising a body, a storage tank, a liquid inlet passage, and a separation unit. A storage tank is formed in the center of the body. A liquid inlet passage is formed in the body and communicates with the storage tank. A separation unit is formed on the body and communicates with the liquid inlet passage. The separation unit includes a stacking zone, a collection zone, and a barrier wall. A collection zone is located between the accumulation zone and the storage tank. A barrier wall is formed between the collection zone and the stacking zone.
